In peritoneal dialysis, the body's peritoneum or abdominal membrane is used as a filter. The dialysis is carried out every day, at home or at work, and the patient can move around during the dialysis (ambulatory dialysis).A permanent tube is surgically implanted in the abdomen through which dialysis fluid can be poured. The dialysis fluid fills the space between the abdominal wall and organs and is left for several hours, after which it is drained from the abdomen.
